Radial component of the spherical accretion parameters as a function of radius r (in units of M) in the presence of a DM halo. These 1D simulations are shown at t/M = 1 000 000 for different coordinates (Schwarzschild, Hernquist, and NFW), with the outer edge of the flow set at r/M = 10⁵. The solid blue line represents the Schwarzschild profile, which represents a static nonrotating BH in a vacuum, without the influence of additional mass like DM. The dashed orange and gray lines correspond to the Hernquist DM profile, and the dot-dashed black and blue lines represent the NFW profile. Both a₀ and M_halo are normalized to the BH mass M.
